Title: Noise suppression nozzles for jet propulsion engines
IPC: F02K1/40
Filed: 1957-01-30
Abstract: 831,152. Jet-propulsion nozzles. BOEING AIRPLANE CO. Jan. 30, 1957 [Feb. 7, 1956], No. 3318/57. Class 110 (3). In a jet-propulsion nozzle the noise is suppressed by means associated with the nozzle outlet to separate the discharge gas flow into a plurality of spaced streams. In one arrangement this is effected by forming a plenum chamber in the nozzle which tapers rearwardly to an end closed to rearward discharge of gas with branch ducts extending outwardly and rearwardly from the tapering portion of the plenum chamber. In another arrangement the nozzle is formed by an outer duct and an inner coaxial member between which are mounted a plurality of flow dividers. The propulsion nozzle 10 is mounted on the discharge of a combustion chamber C. The outside annular wall 12 of the nozzle flares rearwardly at a slight angle. A central member 14 having a tail cone 16 on its rear end forms with the wall 12 an annular channel which is divided into a plurality of radiallyextending orifices 18 by stream dividers 20. The dividers are formed by steel metal walls 20a. A partition plate 24 extending between the walls 20a forms therewith a duct leading air from the atmosphere from apertures 22 to the spaces between the branch jet streams. In a modification, Fig. 5 (not shown), the wall 12 between the dividers 20 is corrugated to increase the nozzle perimeter and thereby expedite the mixture of gases and atmospheric air to further reduce the noise. In another embodiment, Fig. 6, the number of branch orifices is increased. In this arrangement, the exterior nozzle wall 30 has a rearwardlytapering portion 30a which extends to a tail cone 32. The portion 30a carries a number of branch ducts 38 which terminate in discharge nozzles 40.

Title: Tube or bar reducing machines
Inventor: JOHNSON HAROLD JOHN ALFRED
IPC: B21B21/00
Filed: 1959-01-30
Abstract: 899,750. Rolling tubes. TUBES Ltd. Jan. 19, 1960 [Jan. 30, 1959], No. 3330/59. Class 83 (4). In a machine for reducing metal tube or bar in which a pair of rolls having complementary circumferential grooves of progressively varying depth and width are mounted in a reciprocable housing 11 and are synchronously driven by a rack 16 through gearing 15, 14, the rack 16 is also reciprocated by an eccentric 19 so that the peripheral speed of the roll part in contact with the work 18 maintains a fixed relationship with the linear speed of the housing. The eccentric is so formed that the reciprocations of the rack compensate the rotational speed of the rolls for the variation in radius of the contact point with the work so that the instantaneous peripheral speed of the rolls at the point of contact is equal to the instantaneous linear speed of the housing, thus reducing sliding contact to a minimum. The work 18 is stationary during rolling but is incrementally advanced and rotated by a carriage 17 either just before the beginning of the working stroke or at the beginning and end of that stroke. The eccen- . tric 19 and rack 16 are driven through gearing and a shaft 22 by a driving shaft 24 which also operates the crank reciprocating the housing 11. The housing 11 may alternatively be driven by an hydraulic cylinder. Specification 893,797 is referred to.

Title: Process for the manufacture of colourless aqueous solutions of vitamin-k-active compounds
IPC: A61K31/355
Filed: 1943-03-03
Abstract: Colourless aqueous solutions of vitamin K activity are prepared by hydrolysing crude 2-methyl-1 : 4-dihydroxy naphthalene-diphosphoric acid-tetrachloride with water in the presence of a base, precipitating inorganic phosphates by the addition of a calcium compound and heating the solution.  If desired, the 2-methyl-1 : 4-dihydroxynaphthalene-diphosphoric acid calcium salt may be transformed into other salts which, if necessary, are purified by precipitation and re-dissolution in water.  In examples: (1) 2-Methyl - 1 : 4 - dihydroxynaphthalene is dissolved in pyridine and phosphorus oxychloride added and the diphosphoric acid-dichloride separated by extraction with benzene. The benzene solution is concentrated and hydrolysed with aqueous sodium hydroxide.  Calcium chloride is added, the solution is filtered and heated to boiling. (2) A suspension of 2 - methyl - 1 : 4 - dihydroxynaphthalene in toluene and dimethylaniline is added to phosphorus oxychloride in toluene.  The product is hydrolysed by the addition of water, neutralized and calcium chloride added.  The product is then boiled. (3) 2-Methyl-1 : 4-dihydroxynaphthalene is condensed as in example (2), and hydrolysed with water while adding calcium hydroxide.  The product is then boiled.  (4) 2-Methyl-1 : 4-dihydroxynaphthalene is condensed and the calcium salt formed as in examples (2) and (3). Oxalic acid and sodium hydroxide are added until a pH of 6-7 is reached.  The calcium oxalate is removed and the sodium salt thus obtained used directly or purified by the addition of alcohol until an oil just separates and allowing to crystallize.

Abstract: 822,715. Television. MULLARD RADIO VALVE CO. Ltd. Nov. 5, 1956 [Feb. 3, 1956], No. 3539/56. Class 40 (3). In a colour television system simultaneous tri-colour, R (red), G (green) and B (blue) video information is reproduced in line sequential fashion by a picture tube C by means of an arrangement in which the video information relating to the three colour components of each line of the original signal is separately and simultaneously stored in storage devices E1, E2 to respective ones of which such components are supplied during alternate line scans via a switch S 1 which also operates to "gate" on successively the three guns of the storage device in which colour components have already been stored, the guns which are now unmodulated operate to " read " the stored information which is supplied via a switch S3 to the picture tube C. During the " laying-down " or storage process the scanning of the particular device E1 or E2 involved is effected at the line frequency at which the original signals were produced whilst during the " reading " process the scanning is effected at three times this frequency by means of sawtooth scanning waves at such frequencies derived from sources LF and 3LF, respectively, and supplied to the deflection electrodes D1 and D2 of the devices E1, E2 via a switching device S2. Source 3LF also supplies the line scanning waveform for the reproducing tube C, the frame scanning of which is effected at the frame scanning rate of the original signals so that in the reproduced image each line of the original is displayed as a tri-colour group of three lines. Specifications 648,257, 718,652 and 737,030, [Group XL (a)], are referred to.

Abstract: 584,494. Cathode-ray tubes ; tele- -vision. GENERAL ELECTRIC CO., Ltd., and JESTY, L. C. Feb. 28, 1944, No. 3629. [Classes 39 (i) and 40 (iii)] Cathode-ray apparatus in which the incidence of a cathode-ray on a fluorescent screen produces a moving luminous spot, utilized to form a picture for viewing directly or after reflection, or employed as a light-source for scanning a subject or a film, includes means for preventing light from the fluorescent screen from passing to the utilizing means, e.g. the eye or a photoelectric cell, except from the region at or in the neighbourhood of the part on which the cathode ray is incident. The area of the region is a small fraction-for example, one tenth-of the total scanned area of the screen. The shutter or masking means may comprise a rotatable disc with slots, Fig. 1 (not shown), or the cathode-ray tube 10 may be enclosed in a rotatable drum 6 with slots 7 extending over the width of the screen 11, Fig. 1. In a modification, Fig. 4, for scanning a film, the drum 6 has diametrically opposed slots 7 so that the restricted beam from the. tube 10 traverses the gate 15. In a further modification, Fig. 5 (not shown), the drum has narrow slots alternating with wide apertures such that when a slot cooperates with the screen, a wide aperture is adjacent the film gate and vice versa. The slotted disc may be oscillated inside the cathode ray tube and operated electromagnetically. A mirror may be placed within the drum to reflect the light beam axially and the rotating disc or drum may be replaced by an endless belt or by an oscillating disc or grating. When the image is reproduced by reflecting light from a screen, the latter may comprise moving parts so that it is non-reflecting except over the area co-operating with the luminous spot at any instant. The effective slit may be formed ,between the edge of one aperture on one side of the drum and the image of the corresponding edge of another aperture on the opposite side of the drum. For colour television successive slots are covered with a sequence of red, green and blue filters.
